This is a good used unit, removed from an 91 SPG.  This unit is for the single pump cars, US model 16 valve 1990-1993 900 900-S as well as 1990-1993 900-Turbo.  We actually saw this car run and drive, it drove well, and had plenty of power.  This unit is used, but I think it should have a good bit of life left in it, unit was brand new in 2007 (the date code on this unit)

These units typically have a very good lifespan, and the pre pump tends to last longer than the main pimp. This assembly has all, drop this in, and go.  I will also give a 60 day functionality warranty with this unit!  Some of these cars have flat blades, some have round.  I have a pigtail included so you can use it with either.
